2019: Hydrodynamics and gas-liquid mass transfer around a confined sliding bubble

Local investigation of the gas-liquid mass transfer using oxygen sensitive dye. A single vortex leg enclosing transferred oxygen in the confined sliding bubble wake. Angle of inclination of upper wall inclination affects mass transfer. A scaling law between Sherwood numbers and modified Archimedes numbers. Abstract An experimental investigation of gas-liquid mass transfer in the wake of a confined air […]

2018: 2nd International Workshop Non-Invasive Experimental Tools and Numerical Methods for the Investigation of Non-Reactive and Reactive Gas-Liquid Flows

    Faisant écho au colloque Franco-Allemand de juin 2016 organisé à Toulouse, ce second colloque s’est déroulé à Hambourg, dans les locaux de Technische Universität Hamburg (TUHH). Dans ce colloque se sont réunis environ 40 scientifiques (chercheurs, post-doctorants et doctorants, issus de la fédération de recherche FERMaT (14 participants,) et des universités membres du […]

Mass transfer in the wake of non-spherical air bubbles quantified by quenching of fluorescence

 M. Jimenez, N. Dietrich, G. Hébrard, Chem. Eng. Sci. (2013)   Full paper here Abstract Based on planar laser induced fluorescence with inhibition (PLIFI) experiments, the mass transfer behavior in the wake of single rising air bubbles is investigated. Bubbles of equivalent diameters ranging from 0.90 to 2.24 mm are studied, exhibiting vertical and zigzagging paths […]

Gas/liquid mass transfer in Technicolor

Tuesday 10th April 2012, UBC, room CHBE 102, VANCOUVER, CANADA Mass transfer in gas/liquid systems is of prime interest for several areas (medicine, chemicalengineering, environmental purpose, waste water treatment, etc.). Some techniques enable a directvisualization of this complex phenomenon and thus represent a powerful tool for understanding thedifferent mechanisms governing the mass transfer. The purpose […]
